Answer:
height = 12.7 feet
Explanation:
To find the height of the giraffe, we just need to use the tangent relation of the angle of elevation.
The opposite side to the angle is the height of the giraffe, and the adjacent side of the angle is the distance between the giraffe and the narutalist.
So, we have that:
tangent(30) = height / distance
0.5774 = height / 22
height = 22 * 0.5774 = 12.7 feet
